Job performance aids are visual or printed summaries that provide essential steps or information to perform job tasks. Examples include checklists, flowcharts, and procedure manuals. They help ensure training is applied on the job, support effective performance, and reduce time to learn complex tasks. While cheaper than training, job aids are not appropriate if tasks are simple, frequently performed, or if referencing the aid undermines credibility. For best results, aids should be explained during training and used when error consequences are great, tasks complicated, or time/budget for training is limited.
